Norway

The British 148th Bde lands at Andalsnes. Gen Bernard Paget is in command. During the night part of the 5th 'Demi-brigade Chasseurs Alpins' land at Namsos. There has, however, been a mistake made with the equipment for this force and they lack some of the bindings necessary for their skis. This sort of elementary error is typical of the muddled way the whole Norwegian campaign has been conducted and will go on being conducted on the Allied side.

German forces break out of the Oslo area and advance toward Hamar to the north.

The British establish a base at Molde. Troops land at nearby Alesund. Operation Hammer is cancelled. This plan called for a direct assault on Trondheim by the British Home Fleet and the landing of 4,500 troops.

Allied troops from Scapa Flow and the Scottish mainland occupy the Faroe Islands.
